## DESCRIPTION

**SoMotion3Event** represents 3D relative motion events in the Inventor event model.

## METHODS

	**SoMotion3Event()**\
 Constructor.

**static SoType**	**getClassTypeId()**\
 Return the type id for the **SoMotion3Event** class.

**void**	**setTranslation(const SbVec3f &t)**\
 **const SbVec3f &**	**getTranslation() const**\
 Set and get the relative change in translation since the last translation event.

**void**	**setRotation(const SbRotation &r)**\
 **const SbRotation &**	**getRotation() const**\
 Set and get the relative change in rotation since the last rotation event.
